What is the distribution property of multiplication?The distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a given numerical value or factor, the same output would be produced as when each addend is multiplied respectively by the numerical value or factor, and the products are added together.
Note: i² is equal to -1 and i is equal to [tex]\sqrt{-1}[/tex].
By applying the distributive property of multiplication to the given expression, we have:
-3i(4 - 2i) = -3i(4) + 3i(2i)
-3i(4 - 2i) = -12i + 6(-1)
-3i(4 - 2i) = -12i - 6.
-3i(4 - 2i) = -6 - 12i.

Point A is at -7, -3. There are 12 points between A and B. What are possible coordinates for point B?
Answer:
(5,9)
(-19, - 15)
(5, - 15)
(-19, 9)
Step-by-step explanation:
Given that :
Coordinate of point A = - 7, - 3
Number of points between point A and B = 12
Possible coordinate of point B
Possible coordinates of point B:
(-7, - 3) + 12 = (5, 9)
(-7, - 3) - 12 = (-19, - 15)
(-7, - 3) = (-7 +12, -3 - 12) = (5, - 15)
(-7, - 3) = (-7 - 12, - 3 + 12) = (-19, 9)
Hence possible coordinates of be are :
(5,9)
(-19, - 15)
(5, - 15)
(-19, 9)

How do you know if two line segments are parallel?
A. The slope of one is the negative of the slope of the other.
OB. Their slopes are equal.
C. Their slopes are reciprocals.
D. Their slopes are negative reciprocals.
Answer: B Their slopes are equal.
Step-by-step explanation:
Two line segments are parallel if and only if their slopes are equal.
Option B is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Two line segments are parallel if and only if their slopes are equal.
If the slopes of two lines are equal, then they have the same steepness and will never intersect.
However, if the slopes are different, the lines will intersect at some point, and they will not be parallel.
Thus,
Two line segments are parallel if and only if their slopes are equal.

-4.75 = x/2 what is x
Answer:
x= -9.5
Step-by-step explanation:
We want to find out what the variable, x, is equal to. Therefore, we must isolate the variable on one side of the equation.
-4.75 = x/2
x is being divided by 2. The inverse of division is multiplication. Multiply both sides of the equation by 2.
2*(-4.75) = (x/2)*2
2*(-4.75)=x
2* -4.75=x
Multiply 2 and -4.75
-9.5=x
Let's check our solution. Plug -9.5 back in for x and solve.
-4.75= x/2
-4.75= -9.5/2
-4.75= -4.75
This checks out, so we know our solution is correct.
x is equal to -9.5
Answer:
[tex]x = \frac{19}{2} [/tex]
Step-by-step explanation:
[tex] \frac{x}{2} = - 4.75[/tex]
First convert the decimal to an improper fraction
That's
[tex] - 4.75 = - \frac{19}{4} [/tex]
So we have
[tex] \frac{x}{2} = - \frac{19}{4} [/tex]
Cross multiply
4x = - 38
Divide both sides by 4
We have the final answer as

What are some important considerations when conducting cross-cultural research? Is there ever a time when research findings might be free of culture?
Answer:
Following are the relevant factors about cross-cultural research
Step-by-step explanation:
The Cross-cultural also known as the Intercultural studies, it involves work performed across various geographical regions improving student with different cultural backgrounds. While there are several similarities in certain human emotions, feelings, and behavior patterns, delicate differentiation is motivated by religion, political ideology, culture, etc.
It also means that with these distinctions, one could not make assumptions the results to everybody in the world. While most nations are democratic and diverse cos of the enhanced stage of global corporations or organizations, people would stick to their core tenets, traditions, customs or practices, that will make the research difficult to consider as one group. So, cross-cultural research would be the only option and would not shift in the immediate future, as much as the different cultures prevail.Nikki works at a store that sells consumer electronics. She earns $12 per hour, plus a commission of 5% of her total sales amount each day. Nikki worked 8 hours on Saturday. Including her commission, Nikki earned a total of $139 on Saturday. Which equation can be solved for x, Nikki’s total sales amount in dollars on Saturday?
Answer:
See below.
Step-by-step explanation:
So, Nikki earns $12 per hour.
And she also earns a 5% or 0.05 commission of her total sales each day.
On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.
Thus:
[tex]139=96+0.05x[/tex]
Where x represents Nikki's total sales on Saturday.
Further notes:
To solve, subtract 96 from both sides and divide by 0.05:
[tex]139=96+0.05x\\43=0.05x\\x=\$860[/tex]
Thus, her total sales that day were $860.
Two less than a number and five is 12 less than the number itself
Answer: x - 2 + 5 = x - 12
Step-by-step explanation:
At first I was confused. Then I read the question again and translated it.
Less than translated means - 2.
A number, aka X.
and means plus(+).
when you put that together you get,
x - 2 + 5.
The next step is to translate to second part of the equation.
Is means equals(=).
So far we have: X - 2 + 5 = 12.
This is where I got confused...
After solving that peice, we have the words; " 12 less than the number it's self. I wasn't sure if 2 x's could be in the same equation. Now I know they can.
Above, we established that 'a number' is x.
Now, it's talking about that number again because it says; "The number itself." At first, I thought it was talking about 12 - 12! Then I realized that it's not.
The new equation, after understanding that in the second piece isn't 12 - 12, would be none other than,
x - 2 + 5 = 12 - x

Eighty percent of adults drink coffee and seventy percent drink tea. What is the smallest possible percent of adults who drink both coffee and tea?
Answer:
50%
Step-by-step explanation:
Given that Eighty percent ( 80%) of adults drink coffee and seventy ( 70%) percent drink tea.
Let the percent of the adults that drink coffee and tea be y
The total percentage of adults = 100
80 - y + y + 70 - y = 100
150 - y = 100
- y = 100 - 150
Y = 50.
Therefore, the smallest possible percent of adults who drink both coffee and tea is 50 %
A Simpler Answer:
Add together the probabilities.
80%+70%=150%
Therefore we overcounted 50 percent, so the least amount possible is [tex]\boxed{50\%}[/tex]
